Heart Health

Cardiovascular diseases are one of the leading causes of death in men and women worldwide. Heart health can be improved through a balanced diet, with dark fruits being particularly effective in some respects. Let’s take a closer look at the importance of Montmorency tart cherries for cardiovascular health.

A look at the science

Blood pressure

In a study published in the American Journal of Clinical Nutrition, men with early-stage hypertension were giving a concentrated tart cherry product in order to study its effects on systolic blood pressure. [1] The study concluded that “Montmorency Cherry intake acutely reduces SBP in men with early hypertension.” It went on to say that “these benefits may be mechanistically linked to the actions of circulating phenolic acids. “

Another study with 30 healthy, middle-aged men and women between the ages of 45 and 60 was able to essentially replicate the aforementioned effect of Montmorency cherries being able to lower systolic blood pressure. [2] The study condluded by saying that “there was a significant decrease in SBP following Montmorency cherry supplementation when compared with placebo.”

Cholesterol and blood lipids

In women with diabetes, who consumed sour cherry concentrate (40 g per day) for six weeks, a decrease in systolic and diastolic blood pressure compared to the values before supplementation was measured. In the majority of the participants with elevated LDL levels, the total cholesterol and LDL cholesterol levels were also reduced. [3]

A study by the University of Delaware also found that regular consumption of tart cherry juice in the test subjects reduced systolic blood pressure and lowered LDL cholesterol levels. [4]


Supplementation with Montmorency cherries can bring about a wide range of positive effects on the cardiovascular health. A drop in systolic and, in some cases, diastolic blood pressure was almost always measured, and total cholesterol and LDL cholesterol levels were also reduced. The results are promising, even though the scope of the studies should be expanded further in order to secure their evidence, in particular related to the exact components within tart cherries which yield the positive results.
